Abstract	A system of equations for temperatures of electronic gas and lattice around and along the trajectory of a 700-MeV heavy ion of uranium in nickel at the values of thermal parameters, depending on temperature with corresponding initial and boundary conditions, is solved numerically in an axially symmetric cylindrical system of coordinates. On the basis of the obtained lattice temperature dependences on radius around the ion trajectory and depth, it is possible to make a conclusion that the ionization energy losses of uranium ion in nickel are sufficient for melting a material. A comparative analysis with the linear model is given, and the size of the region with maximum radius and depth in the target material, where the melting process can take place, is estimated.
